I just went onto imageshack and found this message:
So much for unlimited uploads. If any of you have pictures stored there, you might want to download them soon, if you don't have them backed up, and find a new host. This is going to be a real pain, because almost all of the pictures on my website are hosted on imageshack.You have 1308 photos stored. Since you're over the 500 photo limit you'll need to upgrade to a Premium account or you'll only be able to keep 500 of your recent photos. Older photos will expire on the 1st of March.
